N-doped porous carbon supported cobalt-ruthenium bimetallic single-atom catalyst for efficient hydrogen evolution reaction
Original language description
Developing a low-cost, high-stability catalyst with electrocatalytic performance comparable to platinum is crucial for advancing the hydrogen evolution reaction (HER) in water electrolysis. Herein, we designed and synthesized a highly active and stable bimetallic single-atom catalyst for the hydrogen evolution reaction. The catalyst features ruthenium and cobalt encapsulated within a nitrogen-doped porous carbon support derived from ZIF-8. Using only a minimal amount of Ru (3.2) alongside non-precious metals like cobalt (8 wt%), the optimized catalyst demonstrated remarkable HER activity, achieving a low overpotential (eta 10) of just 14 mV at 10 mA cm-2 in acidic media. Furthermore, it showed exceptional durability and stability, with no detectable shift in the HER polarization curve even after 1000 cycles. The sustainable performance and outstanding stability under acidic conditions underscore its potential as an efficient catalyst for producing pure hydrogen, providing valuable insights for the design and development of advanced electrocatalysts for proton exchange membrane water electrolyzer applications.
